Her results are stark: Not a single peer-reviewed scientific paper challenged the consensus that climate change is being driven by human activities. Not a single one. She concludes:

Many details about climate interactions are not well understood, and there are ample grounds for continued research to provide a better basis for understanding climate dynamics. The question of what to do about climate change is also still open. But there is a scientific consensus on the reality of anthropogenic climate change. Climate scientists have repeatedly tried to make this clear. It is time for the rest of us to listen.
